DEFINITIONS

VERTICAL LIFT• The lifting of a single plate or structure in which the lifting force exerted

by the rigging is directly above and in line with the pivoting shackle as shown in Figure 1.

VERTICAL TURN/LIFT• A vertical turn/lift clamp is a vertical lifting clamp specifically intended

to turn over a single plate through a ninety degree (90⁰) arc from horizontal to vertical to horizontal in a 180⁰ arc. During the turning operation the edge of the plate opposite to the clamp should always be in contact with something, such as a factory floor. The load to be turned should be less than one half the rated capacity of the clamp. See Figure 2.

PLATE HARDNESS• Unless otherwise specified, lifting clamps are manufactured to lift hot-

rolled steel plates whose hardness does not exceed HB 345 (37 RC).

• Finished and polished plates, such as stainless steel, are generally handled using non-marring clamps with smooth gripping surfaces.

PLATE THICKNESS• The minimum and maximum jaw opening is specified on each clamp.

Never try to lift a plate that does not fit between these values.

LOCKING CLAMPS• Locking clamps feature a locking lever that exerts a force on the finger

cam when the lock handle is moved to the locking position (towards the clamp body). When the handle is moved towards the unlocked position (towards the jaw opening), the force is relaxed and plate can be inserted into the jaws.

NORMAL SERVICE• Service that involves operation with various weights within the rated

load limit with no more than four operations above 65% of the rated load limit per 24 hour period.

HEAVY SERVICE• Service which involves operation within the rated load limit that

exceeds normal service

FIGURE 1

FIGURE 2

SEVERE SERVICE• Service that involves normal or heavy service with abnormal operating

conditions

OVERHAUL SERVICE• After 5 years, in Design Category B lifters, under Normal Service, and

after 3 years under Heavy Service, the lifting clamp will be extensively inspected to determine the condition of the body and all parts.

• If parts need replacement, an authorized repair technician must overhaul the most critical parts, including the finger cam assembly (including spring), the round jaw assembly and the function lever. An ASME compliant approval sticker with year and month will be affixed.

ABNORMAL OPERATING CONDITIONS• Environmental conditions that are unfavourable, harmful, or detrimental

such as excessively high or low ambient temperatures, exposure to adverse weather, corrosive fumes, dust-laden or moisture-laden atmospheres, and hazardous locations.

DESIGNATED PERSON• A person selected by the employer or the employer’s representative as

being competent to perform these specific duties.

QUALIFIED PERSON• A person who, by possession of a recognized degree in an applicable

field or certificate of professional standing, or who, by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve problems relating to the subject matter at hand.

USAGE INSTRUCTIONS

1 CLAMP SELECTION• Select the appropriate capacity and jaw opening size to meet the plate

thickness. The model capacity and thickness rating are indicated on the clamp.

• Never exceed the rated capacity or use on plates that are not within the range of the plate thickness.

• Never lift a load that is below 10% of the WLL of the clamp.• Lift only one plate on each lift.

6 RIGGING CONSIDERATIONS• Plate clamps are components of the rigging used in the lifting or

transporting of metal plates. It is important to use safe and adequate rigging. The clamp is manually held in place until the gripping mechanism of the clamp is activated by a force applied to the pivoting shackle.

• Improper rigging may interfere with the operation of the clamp and its ability to maintain proper position and grip on the plate. Never attach a crane hook directly to the clamp. Instead, use sling between the hook and clamp.

2 INSPECTION• Inspect the clamp before each lift. Complete inspection log if necessary. • Operate the lever to check whether the clamp opens and closes

properly. If the operation of the clamp is stiff or heavy, it should be cleaned and inspected, and possibly removed and repaired or replaced.

• Inspect the clamp opening width. At zero grip, the finger cam should be in full contact with the round jaw. The width at the top of the jaw opening should match the width at the bottom. If it is different, the clamp has been overloaded.

• Inspect gripping surfaces for wear and defects. The finger cam and round jaw assembly’s teeth and rings must be sharp and undamaged and free of debris. Remove debris with a wire brush if needed.

• Check the body, pivoting shackle and finger cam assembly for damage, cracks, or deformation - which might indicate overloading.

• Check all pin holes for wear.• When the clamp is dirty or greasy it can be cleaned with degreasing

solution, then blow dried with air or with a dry cloth at the joints and gripping surfaces.

• Remove any clamp showing signs of wear or damage from use.

7 INSTALLATION OF CLAMP• Operate the lever towards the jaws of the clamp to open the jaws. • Ensure area of the plate that is to have the plate clamp mounted is clean

and free of lubricant, dirt and corrosion. • Insert the plate fully into the jaw.• Operate the lever towards the body of the clamp to secure the plate.

8 POSITION CLAMP• Position the clamp so the direction of force applied from the lifting

mechanism is in line with the pivoting shackle. • Never exceed more than 5⁰ of side loading. See Figure 3. • If using more than one plate clamp to lift a load, ensure the force applied

along the sling or chain is in line with the pivoting shackle. See Figure 4. • Make certain gripping surfaces are in full contact with the plate.

3 PREVENTATIVE MAINTENANCE• Under Normal Service, the lifting clamp and parts will be meticulously

inspected for cracks, deformation, damage and proper functioning by a qualified person.

• During maintenance, the most critical parts (the finger cam and round jaw assemblies, including the spring) must be evaluated and any damaged parts must be replaced.

• All repairs and repair procedures must follow ASME B30.20-2010. • Repaired and maintained lifting clamps must have an approval sticker

with the year and month of service and the name and address of the repairer.

9 LIFTING• Ensure the operator and all persons are positioned away from the plate

being lifted. Do not commence lifting until all personnel are clear of the lifting area.

• Slowly apply tension to the pivoting shackle until gripping surfaces of the clamp are in full contact and exerting a force in the plane of movement.

• Ensure the lifting force is constant and not jerky.

4 COMMON AREAS OF DAMAGE• The finger cam and round jaw are the most critical parts in a plate clamp

and require extra attention during inspection and service. • For the finger cam, reject when the sharpness of one tooth has

disappeared by more than 50%.• For the round jaw, reject when the sharpness of one ring has

disappeared by more than 50%.

10 UNINSTALLING THE CLAMP• After the plate is fully supported and at rest in a stable position, relax

lifting force and manually move finger cam to “open” position by operating the clamp lever toward the jaws. Remove the clamp from the plate.

• Inspect the clamp. Remove any clamp in need of service from use.

5 OVERHAUL PROCEDURE FOR CLAMP• Under Normal Service, the lifting clamp will be extensively inspected to

determine the condition of the body and all parts every 5 years. • During overhaul service, the finger cam and round jaw assemblies,

shafts and function lever must be replaced. • All repairs and repair procedures must follow ASME B30.20-2010. • Repaired and maintained lifting clamps must have an approval sticker

with the year and month of service and the name and address of the repairer.

11 PROCEDURE FOR DAMAGED PRODUCTS• Remove the clamp from service and marked “Out of Service”.• Try to determine the cause of malfunction.

» Excess stress (incidental or structural) » Improper use (unsuitable clamp for the load) » Injudicious use (untrained personnel) » Lifting of new/divergent materials (improper load hardness/dimensions) » Rough or careless use

While this cause of damage is not covered under warranty, it is important from the standpoint of worker safety to understand the cause of clamp failure.

• Give the clamp and maintenance log to your authorized repairer. The repair should be carried out and registered in the maintenance log.

• After the unit is repaired, it must be inspected according to ASME B30.20 paragraph 20-1.3.4.
